Product details
Master Fungicide by Rallis India
Metalaxyl 8% + Mancozeb 64% WP for the listed crop–target uses.
What it controls: The listed downy mildews, blights, tobacco diseases and black-pepper foot rot.
When to use it: Choose the crop and programme first. Spray and soil-drench directions are not interchangeable.
What to include: Use the matching crop programme and current pack directions. Do not add a sticker, fertiliser or pesticide without a verified recommendation.
Why Choose This Product? Key Benefits
- 🌿Systemic component: Metalaxyl provides the systemic component of this two-active fungicide.
- 🛡️Contact component: Mancozeb provides multisite contact activity alongside metalaxyl.
- 🍇Downy-mildew scope: Rallis includes downy mildew in grapes and pearl millet.
- 🥔Defined blight targets: Potato late blight and mustard white rust/Alternaria blight are listed, without assuming every blight is covered.
- 🌱Drench context retained: Rallis describes soil-drench suitability, but each crop needs its own verified programme and rate.
Technical Specifications
| Parameter | Details |
|---|---|
| Brand Name | Master Fungicide | Rallis India |
| Technical Name | Metalaxyl 8% + Mancozeb 64% WP |
| FRAC MoA Code | Groups 4 + M03 | phenylamide + multisite contact activity |
| Chemical Group | Acylalanine (phenylamide) + dithiocarbamate |
| Formulation | WP | wettable powder |
| Toxicity Label | Follow the toxicity colour band, warning and protective-equipment directions on the current pack. |
How It Works: Mode of Action
- Metalaxyl acts inside the plant: The systemic phenylamide component is classified as FRAC Group 4 and acts on RNA polymerase I.
- Mancozeb acts at multiple sites: The contact dithiocarbamate component is FRACM03 and affects several biochemical processes in susceptible pathogens.
- The two components support disease control: Systemic and contact actions are complementary. The mixture does not make metalaxyl resistance irrelevant or authorise unlisted crops or routes.
Compare FRAC groups, not just brands, when planning resistance management. A different brand with the same active ingredient is not a different mode of action. Use only approved crop options and local resistance-management advice.
Target Crops & Pests

| Tobacco (main crop) |
|
| Potato |
|
| Pearl millet |

Dosage & Application Guide
The quantities below are formulation-level references from the Indian CIBRC Major Uses compilation through 30 September 2025, not a current branded pack label or legal approval. Confirm each complete programme against the current pack before use.
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |

*The tobacco-nursery dose and dilution conflict in the reference (5000 g/ha versus 0.1% with 1000 L/ha), so both are withheld. Its listed water and 49-day minimum PHI are retained; route and timing require clarification.
*Grapes PHI is unresolved: an older manufacturer catalogue for the same metalaxyl 8% + mancozeb 64% WP formulation gives 66 days, while the CIBRC formulation reference gives a minimum 7 weeks (49 days). Confirm the current Master pack before treatment; do not choose the shorter interval. Dose, water and explicit concentration are retained as formulation references, not a complete current branded programme.
Tobacco B*: leaf blight/black shank; the reference gives 2000 g/ha or 0.2% with 1000 L/ha and 49 days minimum PHI, describing a soil drench at sowing and a spray 30 days after sowing. However, its crop cell reads nursery while Rallis lists these diseases under main crop. Resolve this stage pairing before either programme; neither is presented as a ready-to-use current Master instruction.
Black-pepper spraying: the formulation reference pairs 2.5 g/vine with 2 L/vine and 0.125%, with a minimum 147-day PHI. These per-vine quantities cannot be converted to acres without a verified planting basis.
Black-pepper soil drenching: the reference separately lists 5 L/vine but does not consistently reconcile that volume with 2.5 g/vine or 0.125%. The drench product rate and dilution are held; confirm before use.
Grape 0.5%, potato/mustard 0.25%, pearl-millet 0.4% and tobacco leaf-blight 0.2% are explicit formulation concentrations in the source; the displayed g/L equivalents are not derived from area rates. Crop-specific routes for grapes, potato, pearl millet and mustard remain unconfirmed.
The reference states minimum waits of 7 weeks (49 days), 8 weeks for mustard (56 days) and 21 weeks for black pepper (147 days). Current-pack re-entry, repeat intervals and maximum applications remain unconfirmed.
Acre figures are approximate conversions of the stated hectare quantities using 0.40468564224. Keep product and water paired. No per-litre or tank rate has been calculated from area rates.
PHI is the minimum time between the last treatment and harvest, not the worker re-entry interval. Follow current label and local restrictions; missing instructions must be resolved before application.
An older manufacturer catalogue describes treatment at disease occurrence/emergence for grapes, pearl millet and potato. This is a separately qualified historical timing reference, not verified current-pack timing, and it does not establish the application route.
How to Apply: Best Practices
- Identify the crop and disease: Keep nursery damping off, main-crop tobacco diseases and black-pepper foot rot as separate programmes.
- Resolve the stated conflicts: Do not use the tobacco-nursery rate, either stage-ambiguous tobacco leaf-blight programme or pepper drench dose until clarified by the current pack/manufacturer.
- Keep concentration and area basis separate: Only the explicitly documented concentrations are shown. Do not translate per-vine pepper quantities into per-acre amounts or assume that every crop is a foliar spray.
- Confirm application details: Follow the current pack for mixing, equipment, crop-specific spray or drench method, timing and re-entry. Manufacturer mention of soil drenching is not a universal drench instruction.
- Plan harvest and resistance management: Observe the verified crop’s minimum waiting period and account for both FRAC 4 and M03 when planning any later approved treatment.
Frequently Asked Questions
1. Does Master contain carbendazim?No. The official Master pack identifies metalaxyl 8% plus mancozeb 64% WP. Do not use a retailer’s contradictory carbendazim description.
2. Is this the same as metalaxyl-M 4% plus mancozeb 64%?No. Metalaxyl 8% and metalaxyl-M 4% are different formulations. Do not copy another brand’s directions simply because both also contain mancozeb.
3. Why are some doses missing?The tobacco-nursery quantities conflict, the tobacco disease stage pairing is ambiguous, and the black-pepper drench dose does not reconcile with its water volume. Only those unresolved directions are held.
4. Can black-pepper spraying and drenching use one recipe?Not on the evidence here. The reference specifies 2 L/vine for spraying and 5 L/vine for drenching, but the drench product dose needs clarification. Both programmes remain listed separately.
5. Can I mix it with other products?No blanket tank-mix compatibility is established here. Use a mixture only when the current labels and qualified crop advice support it; a physical jar test alone does not prove crop safety or legal approval.
